HYDROPANE vs METHYCLOTHIAZIDE AND DESERPIDINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide diuretic; inhibits sodium chloride cotransporter in distal convoluted tubule, increasing excretion of sodium and water, and reducing plasma volume.
Methyclothiazide is a thiazide diuretic that inhibits sodium reabsorption in the distal convoluted tubule, reducing plasma volume; deserpidine is a Rauwolfia alkaloid that depletes catecholamines from peripheral sympathetic nerve endings, lowering peripheral vascular resistance.
50–100 mg orally once daily, maximum 200 mg daily
One tablet (5 mg methyclothiazide / 0.25 mg deserpidine) orally once daily. Maximum dose: one tablet daily.

Terminal elimination half-life is approximately 8-15 hours in patients with normal renal function; may be prolonged in renal impairment.
Methyclothiazide: terminal half-life 17-24 hours, permitting once-daily dosing. Deserpidine: 50-100 hours, allowing accumulation with repeated dosing.
Renal (approximately 50% as unchanged drug) and hepatic metabolism to inactive metabolites; fecal elimination accounts for about 10%.
Methyclothiazide: primarily renal excretion (60-70% unchanged) via tubular secretion; Deserpidine: extensive hepatic metabolism, <1% excreted unchanged in urine, with metabolites excreted in urine (40%) and feces (60%).
